Drag Calculations

• edited blueMaxAnalysis -- added physics of the Drag Equation and used rolling resistance tests. (https://github.com/formulaslug/Sims-Data/blob/43-drag-and-downforce-calculations/Data/blueMaxDragAnalysis.py)
• calculated drag by pulling RR tests and initially creates a speed array, then looks at residuals with the difference of predicted vs actual, then changes our estimates to lower error, and repeats until the values all line up
• Speed vs Time and SpeedxDrag vs Time graphs

Drag Testing Ideas

• accelerate to high speed, shift to neutral, measure deacceleration, and use for better drag and RR calculations (https://github.com/formulaslug/Sims-Data/blob/43-drag-and-downforce-calculations/testing-plan/drag_test.md)

Downforce Calculation

• built downforce calculations using damping forces - validation plot from time 30s-45s
